I tested 53050006 which had P1241 and limp mode anytime (boost more 1.6 bar and gain more 7 with i-color EBC). When i have changed these adjustments we fixed the problem. Tephra, thank you !!!

Exact same issue I am left with here, even without the disbale mod I got my tables to behave perfectly... but launch control triggers a torque limiter limp mode after about 2 seconds of WOT. I did notice a table called "Stationary Rev Limit Cross Under Max Speed Enable Delay" which has 2100ms (2.1 sec) as the default value. Might not be related but the time period sure seems ironic, what does that stat do?
I used to be able to ride the stutter for several seconds without any issue when temps were in the 60's at the drag strip, but in the 90's at the shootout I ran 4 passes and on the 5th it triggered the limp mode for the airflow tables, likely claiming not enough flow for the Throttle position. It was odd that as soon as I lowered my torque limits tables a little lower to similar levels of the airflow limits it switched over to throwing the torque limits limp mode now.

I am seeing a a similar weird reaction to the 2step using these disables as well like LIGHTSPD. Mine doesn't hold and then shoot like his, but it will hold constant until I let off, and then it will go a little nutty. It would drop to 5k, hold there, jump back to 6k, back down to 3k, back up and basically have a wierd surging issue even though I was not on the throttle at all. I would turn the car off and back on and all was well again. I guess the 2step works off of one of the tables/errors in someway? I will try to test this weekend which exact disable this is linked to as I have all 5 you listed disabled at this moment. Going over it, it looks like once I let off the pedal (off throttle APP in my car seems to be 9.611765%) TPS wouldn't drop back to+/- 1% and instead stayed in the 10-11% area causing the RPM to hang. I pushed the clutch in and got it to drop to 2300ish and when I let if back out, it would jump back to 45-5000. Odd...
Also, if you could give a disable for P0140 as it keeps popping up because of my missing rear 02 for whatever reason, even though I have the disable done in the options section. This is using the 0015-20 ROM.

Hmm after talking to Pete at DG Motors it seems that just disabling all the airflow and torque checks for cruise and boosted driving is the way to go. Then dial back the limits on the tables in the 5500-6500 range so that the Launch control won't get aggravated by airflow being too low since you are only hitting 120% load with the launch limiter.
If I can't get my tables to allow for error free launch control that's the path I'm taking.
